Topic: Yellow OLED : high frequency solution (Read 6979 times)

Without the modification described in this thread., some people hear this peak.As you use PCB R5d you already have step 1,2,3 done by just soldering the 22ohm OLED resistor, so the peak is smaller that it was on PCB R5c.If you make a shield as described it will be even smaller.

I made a shield as described, which seems to be working (at least I'm not aware of any noise). I was then sent a shield by Ardi at Vandaal, as it (and a volume knob) had been missing from the kit when it was posted out.

I notice Ardi's shield has a wire soldered to it and I assume that the other end needs to go to Ground or 0V. Any suggestions about the best place to solder this shield to?

Hi! I bought a Preenfm2 from Van Daal. I'm really loving it, but I hear the "OLED noise" and since I don't know anything about soldering and DIY I was wondering if there is a way to delete that freq without affecting the timbre of my patches... may I use an eq? could be enough?
